[Q] Snes Emulation woes - Latency and Emulation problems

Hello all.
I am having problems with emulation on my newly purchased xperia play.
I downloaded snesoid because I was recommended to get it by a friend *and apparently the internet is crazy about it*. When I tried playing Megaman X on it, there was very noticeable slowdown. The first stage *highway* ran at noticeably slower speeds than it did on the snes. It was playable, but felt sluggish. At first I was okay with this, but then I played it on my friend's phone just to test it out, and his was runninghttp://media.xda-developers.com/images/editor/menupop.gif it perfectly.
Does anyone know why that may be?
I also downloaded snes9x ex to test it out, and the app runs great! Problem with this app, unfortunately, is the VERY noticeable input latency. It makes platformers really odd to play on with.
I tried Seiken Densetsu 3 on Snesoid as well, and that game glitches out every conversation that comes up. The screen will flicker for a second. Very jarring.
Has anyone else experienced these kind of things with theirs, and if so, does anyone know a fix for this?
If this is phone specific, I am just going to return it since it only has been a day and just get a new one, but I want to make sure I can't do anything to fix it on my end before hand, this way I can at least learn something about these phones if there is a fix I CAN do at home, since I currently am a huge phone noob.

Something very interesting I just noticed.
Just tried Megaman X2 and X3 and those games run perfectly.
Color me confused.

Yea, SNES9x plays better with less glitches, but has noticeable button lag. Took forever for me to beat DKC, especially the mine cart stages.

Im sorry to hear about your problem mate but mine seems to run all of the games perfectly smooth. Ive had no such issues yet regarding the snesoid emulator.
If you feel strongly about it I would suggest trying out a new sexplay.

Also note the programs you have running in your running services log. Something there may be interfering with your gameplay. I can't seem to use Swiftkey X on my Xplay as it causes lag that kills the experience on nearly every game I play.
But the button lag is something you will have to deal with on any XPlay and SNES9x. Unfortunate, and hopefully will be fixed by the author at some point.

Is there button input lag with Snes A.D (free emulator on market) ?
Could someone test it for me ? I'm supposed to get the phone next week, and I chose it especially for emulation so I'd be disappointed if there are any issues with SNES games.

Have had not any issues with these games.
I use SnesOid and TigerSNES - both free.

same here,gensoid running silky smooth,fpse running perfectly fine,tiger arcade for th e most games also good,but imho useless cause no dip switch access or neo geo rom settings(tried that mame4all but no thanks,seems it support only legacy roms,don`t wanna convert all my roms for that program,the few that were running on mame4all were also laggy)
but snesoid(latest version) isn`t running good,as i stated in another thread.
for example super castlevania 4,it doesn`t matter if frameskip is on or off,set to manual or auto,it`s far away from running smooth,there is a slight stuttering when you look at the background as your character moves forward-also numerous other games..tried snes 9x or what is called,realized it doesn`t load any of my snes roms because it cant read .zip files,only .smc and even with .smc it won`t open some roms.i`ll try this tiger snes now

Hated SNES A.D. looking for a good emu right now too.

when u complain about noticeable input lag in snes9x, what kind of games are u playing? ive never really had any issues with it since its around a 10th of a second (tbh i doubt id ever of noticed it playing things like super metroid)
all of my games are in .zip files and ive never had any issues with the emulator at all, destroys snesoid imo. i do hope that the input lag is fixed, but overall i think its a much better emulator than anything else available.

I sure would like to try snes9x.... can't find it though! Little help?

i noticed just earlier after i posted realizing i hadn't received an update in some time. It appears to have been removed from the market, odd considering that all his other emulators are still there and one of his main selling points was compliance with the gpl of snes9x (the reason it was free as opposed to his other emulators)
the website is http://www.explusalpha.com/home
Robert Brogalia is the devs name, check out his other apps, they all get fantastic feedback.

Oh my god! This emulator is amazing! Everyone get it. This should just come on the phone..... LOL

u can change the dpi of the menus, turn off that shocking linear filtering that snesoid and all them use(i like me some retro blockiness) and it doesnt appear but when scrolling through lists thumb scroll works just fine.

Looks like I have to start over on Zelda, guess the saves are different from snesnoid. So worth it though.
Sent from my R800a using xda premium

u just have to change the extention to the same one used in snes9x...if i recall snesoid uses .sav, snes9x uses .sma or something, i got all mine working so if u fiddle u should get it, afaik quicksaves are a no-go however, just the battery backup works.

Snesoid is based on the snes9x source anyway......

if people are finding solutions that work better for them thats a good thing, i dont care if the source is the same, i find it to be a better emulator. i will say i initially bought all yonghz apps including n64oid.

Goping back on topic i just got myself a Play today, and i have major problems with games on gameboid, genesoid, snesoid theyw ill jump around and skip frames. I know why it's becuase it has frameskip set to 2 by default. If i set it to 0 then the audio produces an annoying stuttering and clicking. I just don't belive this ive seen thousands of videos showing th performance and sound of the games and its perfect. Ive even rooted and stripped my Play of some apps too. Now im really at wits end this thing wont emulate any game perfectly... What can i do????

Trust me mate, I've tried everything on both of my Xperia Plays. One stock, and one overclocked to 1.6ghx with CyanogenMod 7.
I'm at the same stage... I set games to 0 frameskipping and most games run perfectly, however if I enable the sound I get this horrible crackle (and with TigerMAME 3.0.3 noticable lag spikes - which is a damn shame). I think most of these emus need optimising for Xperia Play.
'Perfect' is such an over-used term these days... However these are the best emus of the bunch in my opinion... Trust me, I'm extremely anal when it comes to emulation.
TigerMAME 3.0.3 - With sound disabled can run games like Gigawing and Mars Matrix perfectly. I really hope the audio can be optimised. I'm currently playing the above two games with my own music playing in the background until then. Also, I believe older versions of Tiger run more games than this release...
MAME4Droid - Good for games which fall under the old MAME romset. Most games run smooth with audio (a lot of older games run perfectly) and the amount of CPU/audio customisation is unrivaled.
SNES9X EX - Runs games perfectly (excluding the Mode-7 heavy titles), with only slight audio crackle... Hoping for this to be resolved soon.
MD.EMU - The best Genesis/Megadrive emu around, same dev as SNES9X EX. Does the job where others fail (ie: near perfect Sonic 3 performance). Some audio problems here also.
GBAoid - Seems to work perfectly with everything I've tried. I need to put more research into GBA emu.

[Q] Slowdown in Emulators

Bear with me people as im pretty new to this
Ive got all the decent emualtors onto my Xperia play. SNES / Genesis / GBA / Gameboy etc and they all play fine.
I do notice however that on all the emulators if i set the frame skip to auto, then the sound if perfect, but the frame rate skips sometimes which is more annoyance than anything but still noticeable
If i change the frame skip to zero then the frame rate is buttery smooth but then i get cracks and pops in the sound (all emulators)
Now my question is, is that is this an issue with the emulators or an issue with the play being just not quite quick enough to play these perfectly.
And also, im planning on rooting my phone so obviously if i was to have a slight overclock on my phone, say from 1GHZ to 1.2 or 1.3, would this actually make a difference to them in terms of playing absolutely full speed, or would it make no difference at all?

well thats a tough question,
you can get sound issues when a device is struggling to play a game
and when the device can play the game full speed but the emulator has issues
i too have alot of emulators
marvin - spectrum
gensoid - mega drive
fpse - ps1
gearoid - game gear
tiger arcade
pce - pc engine
snezoid -super nintendo
jarcade - arcade/ mame roms
n64oid - n64
mame4droid
now the only two that gave me sound issues were n64oid and fpse
but since i have rooted my phone and removed bloatware and overclocked
to 1.4
those issues are more or less gone
apart from n64oid do get jittering now and then
but i think that running a n64 on a phone is a feat in itself
yes overclocking does make a difference to running games/emus
more horsepower = smoother gaming
i do recommend rooting
remove bloatware
and overclocking

[Q] Craclking sound with Gamboid and Gensoid?? Can't be!

Hello,
Just got a Play today for use with emulators as it's perfect for physical buttons. But to my surprise there is a lag in it and I mean big time.
By default it's set to auto frame skip max 2, if i leave it like that then the game looks like its jumping really badly but it sounds fine. If i set the skipping to 0 then it runs smoothly but theres this annoying poping and clicking sound on the speakers.
Some people might say i should talk to the developer of the emulators. But this isnt an issue with them, as i dont see any other users with these issues and I don't really belive them to be true when lower devices run these emulators without issues.
I'm running stock formware 2.3.3 latest update. I havent removed any system apps at all literally just bought the play, updated software, loaded emulators and discovered this.

For snes I use supergnes and it has the best sound I have ever seen outside of bsnes, no crackling and a nice front end for launching games.

Thanks that one looks really nice and seems to work better than Snesoid!

Just remove some of the stuff on your homepages, like the game launchers, and the Timescape widget, also the photo and video one too, and the emulators should run better.

I'm making a video to demonstrate the problems. I'll add it to youtube shortly hopefully people can then tell if it's normal or not.
EDIT: Heres the video
Description:
In this video I play Gameboid with pokemon first showing it with frameskip set to auto and 0, and you need to listen carefully to the sound so you can hear that it crackles all the time which is very annoying. I then change the frameskip to 2 which is the default and you can then see that the game skips and jumps and is just too laggy to be belivable.
After that i try out Gensoid and you can see the same results from me running sonic. I get this result with every game i try. I also tried md.emu for sega but it was better but still skipped when the frameskip wa set to auto.
If anyone knows what I can do to solve this please let me know iw ould greatly aphiciate it as i bought the play JUST for emulators, if it doesnt play them then its totally a waste of money for me.

As soon as I got mine, I updated to 2.3.4, and tried Outrun(mame), Sonic 1, and 2 Gensoid), and Contra(Snesoid), both had bad sound, just like on my old phone, which really wasn't up to the job, but on removing Timescape, and that stupid photo and video widget, and the emulators virtual pads, they ran like a charm, Gensoid, Snesoid, and Mame4Droid all work fine, with no sound issues now.
Mame4Droid, I unticked Threaded Sound, as it seemed to cause issues, the others were left with stock settings, bar the virtual screen buttons removed.

I see, I was thinking that i'm the only one with the issues. Well in the end I went to the MIUI build on here and went away from the 'oid' series. Belive it or not but I found Genesis A.D. and MD.Emu to be faster and full speed or at least 99.99%. genplusdroid had a problem it was running slow and also the sound was a tone lower.
Also Snes A.D. seems to be full speed with Chrono Trigger sound included. Have yet to try Snes9x.
SNES: check
SEGA: check
GBC: check
PSX: check
MAME: havent tried
ATARI: havent tried
N64: check
GBA: no dice still lags with gameboid and gba player lite is jumpy, anyone know of another?

FPSE has a bad case of crackling sound... but only if the app is on the background. While you're actually using it there is no problem.

[Q] FPSE and N64oid?

Has anyone here been able to set these up so they run smooth? N64oid has major slowdowns in Zelda and other resource intensive games. I am on HD reveloution where software rendering is disabled so its using the full PowerVR GPU. The Nexus has specs similar to the Galaxy S II and should not perform as slow as it is now.
Also in FPSE the analog sticks dont work and are not centered where you put you finger on the screen. Any ideas?
Also why does using the Microboes or bubbles live background lag the UI soooooo much.

I haven't used FPSE, but I've used n64oid quite a bit over the last few days. It's not 60fps but it's playable, depending on the game. That's not to say it's without bugs...
-Most games seem to randomly experience extreme slowdown and 3+ second hangs. This makes MarioKart and Starfox virtually unplayable at times.
-Sometimes it will sometimes completely freeze at these points of extreme slowdown, to the point where the game needs to be reset. This has gotten me into the habit of saving states FREQUENTLY.
-In Zelda OoT, the camera doesn't move at all in the courtyard of Hyrule castle, so you're effectively stuck at that point, since you can't see where you're going as soon as you walk off-screen. Obviously this isn't specific to the Gnex, but it's worth mentioning for the dev's information

Under the development options in android see if there is a "Force GPU rendering" option and if there is check it and let me know if there are any changes.
I notices if you disable fog and stretch to fix screen on N64oid you see a HUGE performance increase.
Im hoping the dev for FPSE fixes the analog issues soon.

Like others, it seems to depend on the game. Metal Gear Solid is virtually unplayable on psx4droid, and doesn't even load on FSpe. Intelligent Qube works fine on FPse but doesn't load on psx4droid. As for N64oid, MarioKart actually works fine for me outside of a few audio skips here and there, it's pretty responsive. F-Zero X works flawlessly.
One thing I find troubling though is that when I hook up the MHL to HDMI adapter games that once played fine take a noticeable hit in performance. MarioKart becomes unplayable once I hook up the adapter. Does anyone know if the adapter demands more resources (GPU/CPU/RAM/etc)? I would imagine it does since the phone doubles the output instead of redirects it (phone display and MicroUSB out) but I also am not technical enough to really know how this stuff works. It's crummy, cuz playing the N64 and PSX emulators on my projector with a PS3 dual shock controller was one of the major things I was looking forward to with this phone. I see videos on youtube of people doing this on their GSII and it works fine. What gives? Is it ICS?

No its because the gn is pushing 2.4x more pixels than the gs2 and a less powerful gpu.
1280x720 vs 800x480

That has yet to be fully determined. Some ppl hv smoother frame rates than other on the same game but different rom. Though it could be software and hardware related. We need to reach out to the dev (yongzh) and let him know

Forcing GPU didn't seem to make a difference, and actually seemed to crash some emulators. I've kept stretch off because N64 games aren't widescreen, and toggle fog made a VERY slight difference.

Mupen64Plus seems to be running a tad faster than n64oid. just set autoframe skip and max frame skip to 5. BUT the on screen controls keep disappearing and are rather tiny.

You're right, it's definitely running faster than n64oid. But the disappearing controls are obnoxious, and I think the emulator itself needs a little bit of polish. For example, if you lock the screen and wake it back up, it closes the emulator completely. Same if you get a call or something.

Has fpse implemented sixaxis controller app yet? Or using sixaxis or usb contoller period?
Crazy world, ay?

I've been using PS3 dualshock via sixaxis for FPse just fine since I've had the phone. Just have to map it out in the settings.

Ok. I tried recently and it did not work completely. Any suggestions where i might've messed up?
Crazy world, ay?

Use the free sixaxis pairing app to assign the bluetooth address of your phone to the controller (requires hooking your controller up to your computer with a usb cable). Once you've done that, use the paid sixaxis app to actually pair the controller to the phone via bluetooth. Then, within FPse go into settings, input, hardware keys, and just map the buttons. I know you've probably done some of the beginning of that already, but I'm not really sure where you're having problems.

[Q] Tony Hawk 3 and Mat Hoffmans on Xperia Play

Hello,
I've tried to convert the games Tony Hawk's Pro Skater 3 (SLUS 01419) and Mat Hoffman's Pro BMX (SLUS 01113) with PSXperia 2.0. The games inicializated properly in the phone, and ran without any lag, but in both cases, the characters textures were much deformed, making it just unplayable. Somebody get one of these converted games running 100%? I was figuring the possibility of use FPse v0.11.26, but Tony Hawk's ran without sound, and Mat Hoffman's did not get a good fps rate (was slow enough to disturb the game play experience).
Is there anyone who are playing these games and can tell me how to do?
My device is R800i with stock rom, 2.3.4.

I had the same issue with THPS1, I think all the games are affected. Have you tried FPSe? Looks like it may have better luck, maybe not perfect but certainly better.

Yes, i Have tried FPSe, version 0.11.26, but it didnt play the THPS 3 sounds, and its nothing wrong with the rom, in epsxe, for PC, the sounds are played. In Mat Hoffmans, FPSe didnt get a good performance, sometimes the fps falls highly, getting rates under 25.

FPSE v0.11.28 is newly out.
Maybe THPS2 is the best one? I've got THPS1 somewhere, not tried it...
At 1.0GHz I can play in software mode without frameskip, just some occasional audio/music stutter e.g. around the plane on the first level.
At 1.4GHz I can use the OpenGL plugin with music and without frameskip, again with only occasional lag. Frameskip or Boost Mode kills the gameplay. It's kind of my benchmark for testing roms.
So not perfect, but nearly there and playable.
I'm not stock though, currently using Doomkernel v14, Gin2ICS 1.6.9 plus the 15scheduler & 20perfsettings init.d scripts from JokaWild to set and tweak the sio i/o scheduler.
